limestone compressive strength testing organizations

  • Stone Testing

    wet, the strength tests (ie compressive strength, flexural strength, modulus of rupture) are sometimes performed using wet stone specimens For the dry condition, the stone specimens are dried in an oven at 60°C ±2°C (140°F ±2°F) for at least 48 hours or until the weight does not change with additional drying.
